The
second
opportunity
of
the
manual
setpoint
offset
is
the
movement
of
the
setpoint
depending
to
the
current
adjusted
setpoint.
For
this
variant
of
setpoint
offset,
the
object
“manual
setpoint
value
offset”
is
used.
Sending
a
positive
Kelvin
value
at
this
object
causes
an
increment
of
the
current
setpoint.
Sending
a
negative
Kelvin
value
at
this
object
causes
a
decrement
of
the
current
setpoint.
By
activating
the
Setpoint
offset
with
setwheel
at
the
device
‐
specification
with
setwheel,
the
communication
object
number
7
“manual
setpoint
offset
change”
disappears.
The
manual
setpoint
offset
is
performed
by
the
setwheel
now
(have
a
look
at
4.1.1).
The
setting
“max
setpoint
offset”
indicates
the
maximal
possible
setpoint
movement.
If
the
controller
is
for
example
set
to
a
basic
comfort
setpoint
of
3K,
the
setpoint
can
only
be
moved
manual
in
the
limits
of
18°C
and
24°C.
The
setting
“max
setpoint
offset
valid
for”
defines
the
scope
of
the
setpoint
offset.
You
can
choose
whether
the
setpoint
offset
is
only
valid
for
the
comfort
mode
or
also
for
the
night
and
standby
mode.
The
operating
mode
frost/
heat
protection
is
always
independent
of
the
setpoint
offset.
The
setting
„Reset
setpoint
after
change
of
mode”
indicates
whether
a
setpoint
offset
shall
be
maintained
after
a
change
of
mode
or
not.
If
this
parameter
is
deactivated,
the
device
will
switch
to
the
adjusted
setpoint
for
the
chosen
operating
mode
after
every
change
of
mode.
The
communication
object
“Actual
setpoint”
is
for
the
query
of
the
current
setpoint
at
the
actual
adjusted
operating
mode.
